Protestantism is a major branch of Christianity that originated in the 16th century during the Reformation, a movement aimed at reforming the beliefs and practices of the Roman Catholic Church. It emphasizes the authority of Scripture and the importance of faith in Jesus Christ for salvation. Protestantism encompasses a wide range of denominations, including Lutheranism, Anglicanism, and Baptism. Each of these groups has its own interpretations of the Bible and practices, but they all share a common heritage rooted in the desire for religious reform and personal faith.
